Specification of Letters Patent;

ratented May 29, 1906.

Application filed January 2, 1906. Serial No. 294,209.

To all whom it may concern:

Be it known that 1, JOHN A. LOFTIN,a citizen of the United States,residing at Troy, in

the county of Montgomery and State of North Carohna, have inventedcertain new and useful Improvements in Hasp-Locks, of,

which thefollowing is a specification.

The ob ect' of my invention is to provide an improved hasp-lock whichwill embody novel and useful features of construction whereby the haspmay be securedto a staple without resorting to .the common form of pegor sta le latch and which embodies means where y a door or the like maybe readily and expeditiously locked by the useof a hasp and staple.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings, in which- Figure 1 is a perspective viewshowing the Fi 2 is a face viewthereof with the outer plat e removed.Fig. 3 is a perspective view of the ring-like latch employed.

Corresponding and like parts are referred to in the followin descriptionand indicated in all the views 0 the drawings by the same referencecharacters.

Referring to the drawings, the numeral 1 designates the hasp proper, and2 the staple. The hasp in the present instance. consists of the ordinaryplate-like structure, provided with a staple-receiving slot or eye 3,with the exception that it is circularly widened near thestaple-receiving portion and is provided with an upright orperpendicularly-extend ing flange 4, which forms the side walls of acasing for the lock mechanism. This casing is closed at its top by aplate 5, screwed or riveted on the said flange 4 and provided with anopening 6 for the accommodation of a latch-actuating handle and with akeyhole 7. The outer end of the casing-that is, the end adjacent thestaple-receiving eye 3-is open at opposite ends, the said opening beingconstituted by cut-away portions 4 in the portion 4* of the flange 4,and said cut-away portions or openings provide passages for the latch 8.As shown best in Fig. 2, the outer portion 4' of the flan e 4 extends atright angles to the length of the hasp and at right angles to the eye 3to form a stop or limiting means for the latch hereinafter described.

the outer the rear of the The latch 8,as shownin the drawingsmonslsts ofa ringror band a portion of which is .cut away, as indicated at 8, andthis cut away portion is preferably of a width corresponding tothe widthof the eye 3. The band 8 is provided with an inwardly-extending radialarm 8 which is pivotally mounted at its inner end to the hasp 1, themeans of pivoting. consisting inthe present instance of a shank 9 on thelatch-operating handle ,9, which is inserted through the opening-6 inlate, through a corresponding opening in t e arm, and througha-registering opening in the hasp 1. Thelatch-operating .handle 9 ispreferably formed at its outer on for a convenient finger-hold, asshown. By

means of the pivotal mounting of the ringlike latch 8 the same may beturned within the casing of the hasp so as to bring its cutaway portion8 in registry with the eye 3 of the hasp, and when in this position itis manifest that the eye may be inserted over the staple 2.

To secure the hasp to the staple, it is only necessary to turn the latch8 until either end formed by the cut-away portion 8 extends through thestaple, when the hasp will be secured to the staple, as is evident. Inthe present instance the radially-extending arm 8 of the latch is sopositioned with respect to the same that it serves as a limiting meansfor the movement of the latch in one direction in connection with theportion 4 of the flange 4 when the cut-away portion 8 or band is inregistry with the staple-receiving eye 3. Hence in the presentconstruction the latch can be turned in only one direction to insert oneof its ends in the staple. Now in order to lock the latch with its endextending through the staple so as to securely hold the hasp in placeand the door or other part locked I have rovided in the lock-casing atfatch a tumbler 10, which is so mounted between studs 11 that it canshift or reciprocate toward and from the latch 8 and which is providedwith a beveled surface 12 in registry with the keyhole 7. The tumbler 10is springrojected toward the latch by means of a eaf-spring 13, one endof which is seated in a small notch in the casingwall and the other endof which is received in a slot in the tumbler. The tumbler 10 isprovided at its outer end with a notch or shoulder 14 at one side, whichwhen the tumbler is projected toward the latch will spring under one ofthe ends formed by the cutlatch in its circular movement.

From the foregoing description, in connection with the accompanyingdrawings it will be seen that I have provided an 1mproved constructionof hasp in which the atch not only forms a permanent part and is thusnot liable to belost, as are the ordinary peg: usually employed, butwhich may also be 00 ed in its closed position and prevent the unlockinof the door or the like to which my improved hasp is connected except bythe proper manipulation through the instrumentality of a key acting uponthe tumbler 10.

Having thus described the invention, what is claimed as new is- A haspprovided with a staple-receiving eye and with a perpendicular flange theouter portion of which extends transversely of the hasp and is providedwith cut-away porwardly-extending arm of the latch that the opening willregister with said eye When'said arm contacts with the above-mentionedportion of the flange, means for turning said latch whereby to projectit across the eye and a spring pressed tumbler bearing against saidlatch and tending to enter the said opening therein.

In testimony whereof I affix my signature in presence of two witnesses.
